Re: Question: Why use network X.X.X.X 0.0.0.0 area 0?

Most of us do this to not accidentally bring another interface into
the OSPF domain.

The "equivalent" configuration approaches you will often see for the
other IGPs are:

router eigrp 100
network 172.16.1.1 0.0.0.0

and

router rip
version 2
passive-interface default
network 172.16.0.0
no passive-interface fa0/0
